To all whom it may concern Be it known that I, ERNEST C. BARTH, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful improvement in Combined Hot- Water or Steam and Hot-Air Heaters, of which the following is a specification.

rlhis invention relates to certain new and useful improvements in combined hot water or steam and hot air heaters, and the primary object thereof is to provide aI heater of the type mentioned in which the parts are so related as to derive maximum h'eat for the purpose of heating the water to be used as hot water, or for conversion into steam, and for also heating air, so as to thus combine the two heating mediums and lenable use of both for heating purposes, or to enable use of the hot water for cooking or bathing purposes.

A further object of the invention is to provide a heater in which the parts are compactly arranged and related so that they mutually contribute to derive maximum benefit from the heating media.

Still further the invention aims to provide a simple and economical structure which can be easily assembled and maintained in working condition.

In the drawings-Figure 1 is a central vertical sectional view of the invention. Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is an enlarged fragmentary view similar to" Fig. 1. Fig. 4 is a section taken on the line 4-4 of Fig. 3, and Fig. 5 is a section taken on the line 5-5 of Fig. 3,

The invention includes a base structure 1 formed with a circular air box or chamber 2, the base being of ring-sha e, as shown in Fig. 1 and being made of brick-work or cement. Mounted on the base 1 is a supporting element indicated generally by 3. and embodying spaced, inner and outer vertical rings 7 and 9, an inner top part 4 having a central opening 5, and a superposedl top part 6, the top part 4 having a depending flange 4 which overlaps the inner ring 7 while the top part 6 overlaps a ringI 8 which latter in turn, overlaps, the outer rin 9. rlhe flange 4 and the ring 8 are forme with collars or bosses 10, which4 support tubes or casings 11 that are open-ended and Within which the gas burners 12' are disposed. A water tank or drum 13 passes through the posed an opening ofthe top part 4, and has aperlpheral flange 14 which is bolted to said top part 4.A A water inlet pipe 15 is connected to the lower end of drum 13,.while a water outlet pipe 16 is connected to the top of the drum 13. casing or hot air drum 17 seats upon the top part 6 and has an' opening through which the upper end of the water drum 13 projects, so .as to support said upper end of the Water drum. Het air outlets 18 are provided on the top of the hot-air drum l `rllhe top part 4 is provided with a series of spaced bosses 19 which engage the lower ends of a series of vertical tubular members 20, which latter surround the water drum 13 in spaced relation to the latter. A circular manifold 21 surrounds the upper end of the said water drum 13, and is connected to the upper ends of the tubular members 20, the manifold having an outlet 4" which leads to the chimney and which draws 0H the products of combustion from the gas burners.

Arranged within each of the tubular members is a water coil 22, the lower end of which is connected at 23 to the lower end of the water drum 13, while its u per end is connected at 24 to the upper en of the said drum, the upper ends ofthe pipes of which the coils are formed extending through the manifold so as to obtain the benefit of all of the heat which may enter the manifold.

- Secured to the waterdrum 13 about midway of the length of the latter is -a circular deflector late 25 which is horizontally disd) provided with openings through which the tubular members 20 pass. The top part 6 is provided with an opening 26 which surrounds allJof the tubular members and constitutes an air flue.

Air is taken in through the pipe P into the air chamber 2, and thence passes upwardly past the burner tubes or casings 11, and strikes the top part 6, and thence passes through the center opening 26 of said top part, and strikes the deector plate 25, and is then taken olf by the outlets 18. By providing atop vpart 6 which inclines toward the central opening 26 thereof, or which is somewhat conical in form, it will be apparent that the air will thus be directed up in contact with the tubular members 20, which are heated on their interiors by the heat arising from the gas burners 12, and will be esl heated accordingly. The deflector 25 acts" I 2. aheater, i to impart a tortuous path of travel tothe `a hollowsu '13 isv projected downwardly so las to aline and said g v 1,140,289 L the combination of a'base,
